Cisco Cisco Web Security Appliance S370

Cisco Web 
Security Virtual 
Appliance

Cisco offers the Cisco Web Security appliance as a virtual machine that you can 
host on your own network.

The virtual appliance requires a separate license for the virtual appliance purchased 
from Cisco and a Cisco UCS Server (Blade or Rack-Mounted) hardware platform 
running VMware ESXi version 4.x, 5.0, or 5.1.

The Cisco Security Virtual Appliance Installation Guide includes more information 
on the requirements for the virtual appliance.

The new Web Security virtual appliance models and configurations are:

S000V (250 GB disk space, 50 GB cache space, 1 core, 4 GB memory)

S100V (250 GB disk space, 50 GB cache space, 2 cores, 6 GB memory) 

S300V (1024 GB disk space, 200 GB cache space, 4 cores, 8 GB memory)

This feature includes the following changes to AsyncOS for Web:

The Web Security virtual appliance license allows you to clone and run 
multiple virtual appliances on your network.

The loadlicense CLI command for installing the virtual appliance license.

You can use the same license for multiple virtual appliances.

Feature keys are included as part of the virtual appliance license. The feature keys 
will expire at the same time as the license. Purchasing new feature keys will require 
downloading and installing a new virtual appliance license.

Due to feature keys being included in the virtual appliance license, there are no 
30-day evaluations for AsyncOS features.

You cannot open a Technical Support tunnel before installing the virtual appliance 
license.

The version and supportrequest CLI commands have also been updated to included 
virtual appliance information.

There are new alerts and logs for mis-configured virtual appliances.

IPv6 Support

IPv6 is supported in both explicit and transparent deployment modes. The IPv6 
feature is designed to have the same familiar configuration interface as IPv4. 
Existing features such as HTTP/HTTPS/FTP, L4TM, Proxy bypass, URL 
categorization, AVC, among many others all are IPv6 ready. Logs and reports are 
largely unchanged but offer additional visibility into IPv6 traffic.
